Talend Studio provides you with advanced capabilities for analyzing any given item, such as a Job, in the Repository tree view. This implies two forms of navigation: moving forward to discover descendant items up to the target component (Impact Analysis) and moving backward to discover the ancestor items starting with the source component (Data Lineage). The results of the analysis will determine where data comes from, how it is transformed, and where it is going or vice versa.
This feature is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.
